' Specification of Letters Patent. Pgptemtgdl Jan, 26, 11915,

Application filed April 11, 1913. Serial No. 760,420.

To all whom it may concern:

Be it known that I, EDMUND H. RUEHL, subject of the King of Great Britain, residing, at New Hamburg, in the Province of Ontario andDominion of Canada, have invented certain new and useful Improve ments in Sealing-Caps for Bottles, of which the following is a specification.

,My invention relates to a sealing cap for milk bottles and the like, which is readily attachable and detachable; seals the bottle hermetically; provides a protecting flange about the mouth of the bottle; and also permits the bottles to' be carried by means of the finger lugs or wings of the cap.

A further object of my invention resides in the provision of a self-contained sealing cap that produces a hermetical seal; that admits of ready attaching and detaching as well as proper sterilizing thereof, and provides a convenientmode for carrying the bottles when distributing and collecting.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a side elevation illustrating the application of the invention; Fig. 2 is a top plan view of the sealing cap; and Fig. 3 is a vertical sectional view of amilk bottle, partly broken away with the sealing cap in place.

Referring now more particularly to the drawings, wherein is illustrated the preferred form of my invention the numeral 1 designates the main body of the sealing cap, which is of die-drawn metal work, pressed into an annular shape clearly shown in Fig. 2 of the drawings, and having an inner depression 2 forming a peripheral support for a sealing gasket 3; while the outer flange 4 of the said cap, fulfills the double oifice of stifl'ening the sealing cap and forming a protecting flange for the mouth of the, bottles, which in transit are liable to become chipped by impact or contact with an adjoining bottle. The gasket 3 can be made of cork,

rubber, or any composite material, and as seen in Fig. 3, can be readily renewed should occasion demand. Displacement of the said gasket is prevented by the peripheral retaining flange or offset portion 5 of the cap.

The milk bottles, as shown in Figs. 1 and 3 have a peripheral projecting lip 7 about their mouths, while the entrance to the neck of the bottle is enlarged within the said projection, such enlargement forming a seat for the gasket 3, the gasket making a yielding contact with the peripheral wall in the enlarged section of the bottle neck, thereby making the sealing of the bottle hermetical whenever the cap is put into proper place. To retain this cap in place, a leaf spring 8 is riveted to the body 1 of the cap by the rivet 9, and is formed in such a manner as to engage the projecting peripheraljhp 7 .in such a way that the inward or gripping pressure of the resilient spring 8 will hold the sealing cap in proper contact with the bottle mouth. To remove the sealing cap it therefore becomesfnecessary to spread the resilient spring 8 sufficiently for the engaging extremities 10 todisengage the projecting peripheral lip 7 which spring 'is facilitated by two finger lugs or wings 11, riveted I tothe spring 8 as at 12, so that when these finger lugs are pressed together the tips or extremities 10 of the retaining spring are spread, and by pulling on these lugs in a direction away from the bottle at the same time that they are being pressed together, the sealing cap is thus readily and easily removed. When it is desired that the sealing cap be replaced or attached to the bottle, the lugs 11 are again pressed together and the cap pushed intoengagement with the mouth of the bottle, the flaring extremities 10 of the spring 8 aiding their engagement with the projecting peripheral lip 7 It is thus seen that this sealing cap is self-contained, in'that it requires no tools for opening or sealing, and that the, finger lugs 11. being sufficiently curved, permit a convenient mode of carrying thebottles by the insertion of two fingers into them. The bottom or base of the central depression .2 of the sealing cap 1 also provides a convenient place to insert, by stamping, the name of the dairy company by whom the sealing caps are being used.

In reduction to practice, I have found that the form of my'invention, illustrated in the drawings and referred to in theabove description, as the preferred embodiment, is the most eflicient and practical; yet realizing that the conditions concurrent with the adoption of my device will necessarily vary, I desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacri'- ficing an of the advantages of my invention,'as efined in the appended claims.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a sealing cap for bottles, the combination with a bottle having an annular peripheral flange formed upon the upper extremity of the neck thereof, a sealing cap for the said bottle, an annular flange formed upon said cap, the flange overlapping the said peripheral flange of the bottle, aleaf spring arranged upon the said cap and secured thereto, extensions formed upon the spring extremities adapted to overlap the annular flangeof the cap and engage the under faceo'f. the peripheral flange of the bottle, and means including a pair of spaced apart spring lugs carried by the said spring,

the operation'of the said lugs adapted to release the engagement of the said spring extremities and the said peripheralflange, and'for the purpose set forth.

2; In a'sealing cap for bottles, the combination-with a 'bottle having an annular peripheral flange formed upon the upper extremity 'of the neck thereof, a sealing cap including a body ortion adapted to form a closure for said ottle, the said cap hav- "upon the said caping an annular depression formed conoen tricallyx therein and extending into the mouthof the bottle, anannular retaining flange formed upon theperiphery" of the said body, said flange overlapping the said peripheral flange, "a leaf spring arranged and secured thereto, extensions formed uponthe spring extremities adapted to overlap the annular flange "of the cap and engage theunder face of the peripheral flange-of the-bottle, and means Including a pair of spaced apart lugs carried the operatlon of the said lugs releasing the spring extremities, from engagement with the peripheral flange, as and for the purpose set forth.

3. In a sealing cap for bottles, a cap having an annular depressed portion adapted for engagement with the interior wall of the bottle neck, an annular peripheral flange adapted for engagement with the exterior wall of the bottle neck, and spring retaining means aflixed'to the cap, said means being engageable with both the wall of the depressed portion and the annular flange to maintain the former in engagement with the interior wall of the bottle neck and the latter in engagement with the exterior wall pf tllile bottle neck, as and for the purpose set ort 4. In combination with a bottle having an annular peripheral flange formed upon the upper extremity of the neck thereof, a sealing cap including a body portion adapted to form a closure for the said bottle, the said cap having an annular depression formed concentrically therein and adapted to extend into the mouth of the bottle, a gasket arranged between the inner face of the bottleneck and the outer face of the annular depression, the said gasket fitting within a depression formed within the said bottle, an annular ret'a' flange formed upon the periphery of the said body adapted to overlap the said peripheralflange, a leaf spring arranged-upon the said cap and secured thereto, extensions formed upon the spring extremities adapted to overlap the annular flange of the cap and engage the under face of the peripheral flange of the bottle, and means including a pair of spaced apart'spring lugs secured to the said spring, the operation of the said lugs adapted to release the engagement between the said spring extremities and the said peripheral flange, as and for the-purpose set forth;

In testimony whereof I aflix my signature in presence of two witnesses. I ,7 EDMUND l1 RUEHL, cw m= omw rrm, r
